I have the basics to get started in electronics: Digital multimeter, soldering iron, solder sucker, calculator, helping hand, scientific calculator, a laptop well equipped with Google, a few MCUs, sensors and actuators, etc.

But I'm starting to miss the tools to leap forward and see voltage in the time domain, aka oscilloscope. It would be so helpful to see this i2c data on the scope screen. I think the lack of it is holding me back.

A professional power supply would improve the safety of my setup, but really what I can't wait for is to get my hands on an oscilloscope. Do you think the Mando can repair its ship without one? Lulz.
